1. 1. Hardware Subsystem Proposal of an Off-Vehicle Battery Analyzer from a Charging/Discharging Perspective

   University essay from Högskolan Väst/Institutionen för ingenjörsvetenskap

   Author : Rinor Gashi; Tim Johansson; [2023]
   Keywords : battery electric vehicles; power conversion module; off-vehicle battery packs;

   Abstract : Electric Vehicles (EVs) are seen as one of the solutions to some of the world’s global current problems, such as global warming and air pollution, due to non-existent operational emissions and increased efficiency. There are multiple types of EVs, one of them being Battery Electric Vehicles (BEVs) which in most cases utilizes a Li-Ion battery pack as energy storage. READ MORE

3. 2. Pulse Charging of Li-ion Batteries for Enhanced Life Performance

   University essay from KTH/Kemiteknik

   Author : Josefin Strandberg; [2023]
   Keywords : Li-ion battery; Pulse charging; Cyclic aging; Capacity fade; Internal resistance; Battery impedance; Litiumjonbatteri; Pulsad laddning; Cyklisk åldring; Kapacitetsminskning; Inre resistans; Batteriimpedans;

   Abstract : Det överhängande behovet av att minska utsläppen av växthusgaser för att uppfylla Parisavtalet har väckt ett ökat intresse för elektrifiering som en strategi för att mildra klimatförändringarna. Litiumjonbatterier spelar en central roll vid elektrifiering och har framträtt som det primära alternativet för batteridrivna elfordon. READ MORE

4. 3. State of charge and heat impact on Li-ion batteries during calendar aging

   University essay from Uppsala universitet/Signaler och system

   Author : Martin Jonsson; Tobias Karlsson; [2023]
   Keywords : State of charge; SoC; calendar aging; heat impact; Li-ion;

   Abstract : Rechargeable batteries that are powering our everyday electronics go through their lifetime with countless charge/discharge cycles, after a few years the capacity has dropped noticeably. But how about batteries that are working as a back-up power system for when connection to the AC mains is not possible, they might only perform a handful of cycles but does this mean they last forever? On behalf of Getinge AB, this bachelor thesis aims to explore the subject named as ‘calendar aging’. READ MORE

5. 4. Operando detection of Li-plating by online gas analysis and acoustic emission monitoring

   University essay from Uppsala universitet/Strukturkemi

   Author : Inti Espinoza Ramos; [2023]
   Keywords : Li-ion batteries; graphite; solid electrolyte interphase; lithium plating; online gas analysis; operando acoustic emission monitoring;

   Abstract : Lithium ion batteries (LIBs) are widely used for storing and converting chemical energy into electrical energy. During battery operation, lithium ions move between electrode materials, enabling energy storage. However, aging mechanisms like lithium plating can negatively impact battery performance and lifetime. READ MORE

6. 5. Optimal aging-aware battery management using MPC

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Raphaël Turquetil; [2022]
   Keywords : Li-ion battery; Fast-Charging; Aging; Model Predictive Control; Li-ion-batteri; snabbladdning; åldrande; modell prediktiv regler;

   Abstract : The freight transport plays an important role in the development of the economy. However, this comes with an important contribution to greenhouse gas emission. Recently a shift toward heavy-duty electric vehicles has been made, but some issues still need to be tackled. READ MORE
